D-Link xStack DGS-3627

D-Link xStack DGS-3627 ... copper modules. In this configuration, one or two 10-Gigabit uplinks may be created, depending on whether the linear or fault-tolerant ring stacking1 is implemented. Up to 12 switches can be stacked in this way.

Using the low-cost coaxial cable as the medium to stack switches together provides not only high-bandwidth stacking but also the flexibility to add 10-Gigabit uplinks strictly as needed. The three open slots can also be used for optional 10-Gigabit XFP fiber uplinks to servers or a backbone connection.

With D-Link Single IP Management (SIM) support, you can easily add up to 32 switch units -regardless of the model- in a virtual stack in addition to your physical stack. Multiple switches can be configured, monitored and maintained from any workstation running a Web browser via one single IP address. The stack is managed as a single object, as all stacked units are identified by a single IP address. A simple yet powerful web-based interface allows you to perform most management and configuration tasks.

A complete set of security features is provided, which includes L2/L3/L4 multi-layer Access Control Lists (ACLs) and 802.1X user authentication via TACACS+ and RADIUS servers. The switch also offers suppression capabilities and Layer3 IPv4/v6 static routing to increase network performance and security. In addition, when implemented in conjunction with a D-Link NetDefend firewall, this switch as a stand-alone or in a stack, is able to automatically quarantine any host displaying abnormal behaviour. Finally, D-Link's ZoneDefense, provides proactive network security by preventing viruses from spreading through the network and thwarting harmful network attacks.

The DGS-3627 switch provides VLAN support including GARP/GVRP and 802.1Q to enhance network security and performance. The switch implements a robust set of multi-layer (L2, L3, L4) QoS/CoS features to ensure that critical network services like VoIP, ERP, Intranet and video conference are prioritised. Bandwidth control allows administrators to set traffic limits on each port, ensuring a committed level of service for end users. For advanced applications, per-flow bandwidth control allows easy fine-tuning of service types based on specific IP addresses or protocols. In addition, a unique feature, D-Link Safeguard Engine, allows administrators to configure thresholds that limit the impact of packet flooding typically caused by virus/worm outbreaks. This increases the switch's reliability, serviceability and availability.
